This model has been printed, built and has stood the test of time.It requires a huge printing space and there are no customizations done to the model to make post-print assembly easier.These models have not been properly sized, however, I will include the measuring stick and properly sized sunglasses to make sizing easier for you.The measuring stick is based on the length of my printed mask.Adjust your wall thickness on the printer to accommodate the lack of wall thickness on the majority of pieces.
